8 Clai ns (01. z s9) This invention relatesin itslbroader aspect to unions or jointures for securing together separable elements, while it has especialreference to connectors or couplings useful in attaching 5 faucets or spigots to barre1s,t'anks, drums, carboy bottles, andchemicalstorage containers.

I More particularly my invention'refers to connectors or couplingsvmadeof rubber or similar material; which can beiemployed forfisecuring a. faucet or spigot to the outlet of a tank or other fluid container. 1 H

t The primary object of this: inventiorixis to pro vide a connector or coupling of thenotedcharacter. wherebyla; .jointure absolutely free .from any leakage tendency is easily-effected with a expenditure of time and labor, and further. without the aid or bolts, screw threads 1 or their equivalents, which arexextremely objection able from the standpoint of fostering-deterioration "corrosion; such fastening means being also exceedingly imp rubber lined, containers. 1

in connection' with tools. 1

V'I'he stated and other, incidental 1 objects are attained by means of the structures, combinations and arrangements ofpartsiihereinafterfully dis closed and claimed; andJin order that theisame may bethe better understood, reference is had to the accompanying sheet ofexplanatorydrawspecification. 1

I In all the'views similar reference characters designate the-same or correspondingparts.

. "In theembodiment of :my invention shown by Figs. I to V, inclusive, the numeralldesignates axside wall}. of a conventionally constructed woodenttank, having an inwardly tapered outlet 2. Thetank is conveniently, although not essentially, lined with a rubber or similar coating .3.

Fitting'snugly in the tapering outlets is an aperture liner'or' sleeve 4 of rubber, molded or otherwisesuitably formed. This liner or sleeve iisrheld firmly" in theside-wall 1 by suitable securing means, such as integrally-formed inner and outer flanges 5, 6, respectively. The joint between the wooden wall 1 and the innerflangefi is protectedby thecoatingof rubber 3 to properly v seal it against injurious action of the tank contents; while said sleeve is providedwith an inner rectangularrsection groove' "7, intermediate the flange ends 5,6, for a purpose later on explained. The outer flange 6 is conveniently, although not essentially, inset *flush 'with'the outer face of the wallL-a I Adapted for :c'oaction with the liner :or sleeve 4 isa, hollow collapsible rubber connector 8, having atone end of its varying diametric dimensi'ons an enlargementwith an encircling rib 9 of a diameter -'which is greater than the major diameter of theopenin'g' throughthe sleeve 4, in the tapering outlet 2, in which it is fitted. Attention is, at this juncture, particularly directed to the fact that theeicterior dimensions at the ribbed end of the connector B, relativeto the liner or sleeve 4 areso predetermined that the two will properly register after said connector is inserted inplace. l

In order to insert the liner-or sleeve4,it is only necessary to collapse the same by pressure be-- tween the fingers to an extent suflicient to permit its passage intopositionin the tapering outlet .2, whereupon it will automatically expand into proper sealingrelation therein. Now as will be easily understood'from Fig. II, after the liner or sleeve '4 is seated or secured in the tapering outlet 2, by asimilar collapsing of the ribbed end of the connector 8, the latter can be easily inserted into place with the encircling rib 9 of similar section lockingly-engaged in the sleeve-groove 7. The thickness of the walls of the rubber connector 8, as well as its inherent pliability, obviously, is such as to permit said connector being contracted sufiiciently to enter the liner or sleeve 4 in the manner stated.

Adapted for coaction with the connector 8 is the hardrubber or glass cook or spigot 10; having in its shank 11 an encircling "rectangular-section groove 12, of a diameter slightly greater than an inner rectangular-section rib 13 molded in said;..

Attention is particularly. .dir'

connectors bore. rected to the fact that the dimensions'of the hard ister after said spigot has been inserted. .';3Fulthermore, the dimensions of the connector 8 and the encircling :ribz- 9 are such that, at this end, it is under compression; while-the dimensions of saidconnector at-theend with-the rib 13 is under tension, which holds the spigot 10 firmly in place free from leakage. The locking effect ofthe'rib 13. is -further augmented bysthe provision of a circumferential rim 14, molded onithe outside ofv the connector 8 to increase the pressure between thegi'oove 12of the spigot loandithe rib 13 of said connector. I It will be obvious that :when the spigot'z-lo; is in'position', .the connector .8 is locked in the. outletlinenor sleeve eat one end, .while the connectors-8', at-thezother end; locks said spigot inplacer 1.

-While the inherent. resiliency-of the rubber safetyring 15. --.'Ihis: ring-151s forcedover the connector; 8:before"=it is inserted in :the aperture liner or sleeve ;4;'. and. it is conveniently made. of metal-such, as "brassior any other desirable substance which is relatively; noneyieldin'g in. charace 11812:": The; inside diameter of the ring is the same or; ashadezless thanthe outside-diameter of the: connector. '8 where it 'is;adjacent.. to the lip or. rim-14, after? the. spigot .10 has been pushed into ,place; Before-the spigot 10ihas, been in; serted, the safety ring 15 is positioned on the connector 8 away from the rim 14 as far as possible, whereupon said spigotis insertedand the-ring 15 pushed up against the. rim 14, which incidentally actsas a-stop. 3;1t;is' obvious that the SDiQOt'; 10 is now,:'what may, be; termed, double-locked? "in the connector 8-,.as itis impossible to get the rib 13 up? over the side-wallspof the groove 12, which is necessarybeforeisaid spigot canbe withdrawn fromthe connector 8. 1 '1 While the safety, ring 15,;J'ust described, is con+ tinuous throughout its circumference, it is evident it. may besplit at any one point of iits cire cumference and; still function, provided thereafter its rigidity has not been so weakened, that it can be sprung sufiiciently to allow the; rib 13 toride up; over the sidewalls of the groove 1211-, :To, remove, the spigot 10. from-the connector '8, thesafety-ring115 .is first pushed back towards the tank outleta, then :by exerting thenecessary force on said spigot, the rib-i13 rides upoverjthe side walls; of the-groove l2-,,whereupon said spigot may be easily. withdrawn. The. connector 8? is then-pulled out from the tankeoutlet' lineror sleeve 4, by collapsing it between the fingers to disengage the rib 9 from the groove 7 in said sleeve, and then pulling outwardly.

In the modified form of my invention shown in Figs. VI and VII, the aperture liner or sleeve 4 is dispensed with, and the tapering outlet 2 provided with a rectangular-section groove 16 for reception of the connector encircling rib 9, in an obvious manner. In addition thereto the connector 8 is provided with' one or more qradiallydirected exterior lugs or projections-17,for passage through' registrable correspondingly-configured notches or grooves 18, longitudinally of the safety ring bore. Now it will be readily ap- "parentthat, after the safety ring 15 is forced rubber spigot 10 and the groove 12, ;relative1to' the interior dimensions or boreof the conneotor 8, are so adjusted that the two will properly reg- ,into abutment with the connector circumferential rim14, by imparting a quarter turn, for ex- "ample, to said safety'ring, the grooves 18 will be i :moved out of registration with the projections 1'7,

bayonet-fashion; whereupon the safety ring 15 will be double-locked,'as it is impossible to now force the side wall of the spigot shank groove 12 over the connector rib 13.

While the foregoing description has made reference. to an emptyingcock attached to the outlet of a rubber-lined barrel, or storage tank, it is equally apparent that my invention is likewise applicable to glass bottles,-or carboy bottles,.steel drumspand other containers; hence'I do not desirezto limit myself to the precise details of construction set forth and shown; but include hereinsuch other forms of the invention as may be effected by those conversant/with the art, providingsuch other forms be within the scope of the-following. claims.-
